Grandiflora rose plant named ‘WEKpupmobalip’

ABSTRACT

A new variety of Grandiflora rose suitable for garden decoration, having flowers of gold suffused with pink coloration.

Classification: The present invention relates to a new Rosa hybrida plant.

Variety denomination: The new plant has the varietal denomination ‘WEKpupmobalip’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Grandiflora Rose. It has a non-disseminated seedling of my creation as its seed parent with the following genetic origin Pumpkin Patch x (Moonstone x Baby Love) and as its pollen parent the variety known as ‘WEKjucistwe’ (U.S. Plant Pat. No. 31,861).

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from other presently available and commercial rose cultivars known to the inventor are the following combinations of characteristics: its elegant old-fashioned flowers of gold suffused with pink coloration, its strong fruity and spices fragrance and its excellent color stability throughout the life of the flower. The plant has an upright somewhat spreading growing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in Kern County, Calif., shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding asexual propagations. ‘WEKpupmobalip’ may be asexually propagated by cuttings, budding and grafting. The budding and grafting successfully occurred on the plant/rootstock Rosa hybrida cv. ‘Dr. Huey’ (not patented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, a non-disseminated seedling of my creation by the following combination of characteristics: whereas ‘WEKpupmobalip’ bears very double flowers (about 54 to 146 petals) of gold suffused with pink coloration, the non-disseminated seedling bears double flowers of soft orange coloration with significantly lesser petalage (about 24 to 28 petals). The new variety bears flowers with a strong fruity and spices fragrance, whereas the seed parent bears flowers with a light tea fragrance.

The new variety may be distinguished from its pollen parent, ‘WEKjucistwe’ by the following combination of characteristics: whereas ‘WEKpupmobalip’ bears medium to large sized flowers (about 8.3 to about 10.7 cm. in diameter) of gold suffused with pink coloration, ‘WEKjucistwe’ bears significantly smaller flowers (about 7.0 to about 9.0 cm. in diameter) of yellow blushing pink coloration. The new variety bears very double flowers (about 54 to 146 petals), whereas the pollen parent bears flowers with significantly lesser petalage (about 45 to 65 petals).

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The new variety may be distinguished from its closest commercially available cultivar, ‘AUSnyson’ (U.S. Plant Pat. No. 22,171) by the following combination of characteristics: whereas ‘WEKpupmobalip’ bears medium to large sized flowers (about 8.3 to about 10.7 cm. in diameter) of gold suffused with pink coloration, ‘AUSnyson’ bears significantly smaller flowers (about 7.5 cm. in diameter) of salmon-pink coloration with a golden-yellow reverse. The new variety bears flowers with a strong fruity and spices fragrance, whereas the closest commercially available cultivar bears flowers with a strong tea fragrance.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows the flowering thereof from bud to full bloom depicted in color as nearly correct as it is possible to make in a color illustration of the character. The branches used for the photograph came from 3 to 4 year-old rose plants of the new variety grown outdoors in Wasco, Calif. in the month of November. Throughout this specification, color references and/or values are based upon The Colour Chart of The Royal Horticultural Society (1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the new variety grown outdoors in Wasco, Calif. in the month of November. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

-   Flower: The new variety usually bears its flowers singly, sometimes     in clusters of two to five per stem. Flowers may be borne in regular     rounded clusters on strong somewhat short to medium length stems     (about 23 to about 44 cm.). The cluster ranges from about 16.0 to     about 20.2 cm. in diameter. Outdoors, the plant blooms abundantly     and nearly continuously during the growing season. The flowers have     a strong fruity and spices fragrance. -   Bud: The peduncle is about 1.4 to about 6.2 cm. in length, of     average to somewhat heavy caliper (about 0.2 to about 0.4 cm. in     diameter), and usually erect. It is somewhat rough, with few     stipitate glands. Peduncle color is between 146C and 146B sometimes     lightly suffused, especially on the side exposed to the sun, with     between 187B and 187C. Before the calyx breaks, the bud is about 1.2     to about 1.6 cm. in diameter at the widest point, about 1.4 to about     1.8 cm. in length, and moderately ovoid to somewhat pointed in     shape. The surface of the bud bears between 8 to 12 foliaceous     appendages with few stipitate glands and numerous hairs, usually     with stout much cut foliaceous parts extending beyond the tip of the     bud about ¾ or more of its length. Bud color is between 137C and     137B. The sepals are 5 per flower, about 1.8 to about 4.4 cm. in     length and about 0.8 to about 1.2 cm. in width at the widest point.     The outer surface color of the sepal is between 137C and 137B. The     outer surface of the sepal is mostly smooth and bears between 0 to 5     foliaceous appendages with few stipitate glands and numerous hairs.     The inner surface color of the sepal is near 146C broadly bordered     by near 137B. After the sepals open, the inner surface color is     often lightly suffused, especially on the area exposed to the sun,     with between 187B and 187A. The inner surface of the sepal is     covered with fine wooly tomentum; sepal margins are entire and lined     with few stipitate glands and numerous hairs. The sepals are     fugacious, and usually straight in shape with acute apices. The     receptacle of the flower is of somewhat short to medium length     (about 0.4 to about 0.9 cm.) and average in caliper (about 0.7 to     about 1.2 cm. in diameter). The receptacle is cup-shaped in form.     Its surface is smooth with somewhat thick fleshy walls. The     receptacle color is between 144A and 137C. As the petals open (after     the calyx breaks), the bud is about 1.5 to about 2.8 cm. in diameter     at the widest point, about 1.8 to about 2.6 cm. in length, and     globular to somewhat ovoid in form. The color of the under surfaces     of the newly opened petals is between 1C and 13C often heavily     blushed on the outermost petals with between 53A and 60A. There is     no visible change in coloration at the point where the petal     attaches. The color of the upper surfaces of the newly opened petals     is between 48A and 51B. At the point where the petal attaches, there     is a large zone of between 154C and 1B. -   Bloom: When fully open, the bloom ranges from about 8.3 to about     10.7 cm. in diameter. Petalage is very double with about 54 to 146     petals and about 14 to 126 petaloids irregularly arranged. When     partially open, the bloom form is moderately high centered to     somewhat globular to cupped, and the petals are moderately tightly     spiraled to cupped with petal edges somewhat reflexed outward. When     fully open, the bloom form is more cupped, and the petals are     loosely cupped to somewhat undulated with petal edges somewhat     reflexed outward. -   Petals: The substance of the petals is heavy and of medium to     somewhat thick thickness, with upper surfaces moderately satiny and     under surfaces slightly shiny. The petals are about 2.3 to about     5.5 cm. in length and about 1.7 to about 4.7 cm. in width at the     widest point. Petal margins are entire. The outer petals are     moderately obovate to somewhat rounded in shape with rounded apices.     The inner petals are broadly obovate in shape with rounded apices.     Petaloids are about 0.6 to about 4.2 cm. in length and about 0.4 to     about 3.1 cm. in width at the widest point. Petaloids are     irregularly shaped moderately obovate to somewhat oblanceolate to     subulate with rounded to sometimes lacerated apices. -   Newly opened flower: The under surface color of the outer and     intermediate petals is between 10D and 19C. There is no visible     change in coloration at the point where the petal attaches. The     upper surface color of the outer and intermediate petals is between     4C and 3D often moderately suffused with between 68C and 50A. There     is no visible change in coloration at the point where the petal     attaches. The under surface color of the inner petals is between 10D     and 19C. The upper surface color of the inner petals is between 4C     and 3D often heavily suffused with between 64D and 50A. The under     and upper surface colors of the petaloids are similar in coloration     to the upper and under surfaces of the inner petals. The general     tonality of the newly opened flower is between 4C and 3D often     heavily suffused with between 64D and 50A. -   Three-day-old flower: The under surface color of the outer,     intermediate and inner petals is between 8D and 19C. There is no     visible change in coloration at the point where the petal attaches.     The upper surface color of the outer, intermediate and inner petals     is between 4D and 2D often moderately suffused with between 68C and     51B. There is no visible change in coloration at the point where the     petal attaches. The under and upper surface colors of the petaloids     are similar in coloration to the upper and under surfaces of the     intermediate and inner petals. The general tonality of the     three-day-old flower is between 4D and 2D often moderately suffused     with between 68C and 51B. On the spent bloom, the petals usually     drop off cleanly. In November in Wasco, Calif., blooms on the bush     growing outdoors generally last about four to five days. Cut roses     from plants grown outdoors and kept at normal indoor living     temperatures generally last about four to five days. -   Male reproductive organs: Stamens are many in number (average     about 95) and are arranged regularly about the pistils; some are     mixed with petaloids. The filaments are of somewhat short to medium     length (about 0.4 to about 1.0 cm.) most with anthers. Filaments are     between 6B and 5A in color. The anthers are moderately small for the     class and all open approximately at the same time. Anther color when     immature is near 22A on the external part and near 10D on the     internal part. Anther color at maturity is near 164A on the external     part and near 200A on the internal part. Pollen is abundant and     between 18B and 16D in color. -   Female reproductive organs: Pistils vary in number (average about     165). The styles are moderately uneven, average to somewhat long in     length (about 0.4 to about 1.1 cm.), thin in caliper, and loosely     bunched to somewhat separated. Stigma color is between 12A and 13B.     Style color is between 1D and 154D often heavily suffused with     between 60A and 60B. Ovaries are usually all enclosed in the calyx.     The ovaries are of small size and between 158A and 158B in color.     Hips are of moderately short to average length (about 1.2 to about     1.7 cm.), flat at the top and moderately globular in form, and     between 31A and 30A in color when ripe. The hip surface is smooth     with somewhat thin fleshy walls. The seeds are irregularly rounded,     smooth in texture, approximately 25 to about 36 per hip, about 0.4     to about 0.6 cm. in diameter at the widest point and between 164C     and 161B in color. -   Foliage: The compound leaves are usually comprised of three to seven     leaflets and are borne abundantly. The seven-leaflet leaves are     about 7.6 to about 14.8 cm. in length and about 5.2 to about     10.4 cm. in width at the widest point, moderately leathery to     somewhat crisp in texture on both sides, and glossy in finish on the     upper side and semi-glossy in finish on the under side. The leaves     have a pinnate venation pattern. The terminal leaflets are about 2.8     to about 6.2 cm. in length and about 2.5 to about 4.2 cm. in width     at the widest point, shaped moderately rounded to somewhat ovate     with moderately acute to somewhat cuspidate apices and moderately     cordate to somewhat rounded bases. Their margins are usually simply     serrate. The upper surface color of the mature leaf is between 139A     and 137A. The under surface color of the mature leaf is between 146A     and 147B. The under and upper colors of the leaf veins on the mature     leaf are similar in coloration to the upper and under surfaces     colors of the mature leaf. The upper surface color of the young leaf     is between 137B and 137C, often heavily suffused with between 187A     and 187B. The under surface color of the young leaf is between 146B     and 147B, often heavily suffused with between 187A and 187B. The     under and upper colors of the leaf veins on the young leaf are     similar in coloration to the upper and under surfaces colors of the     young leaf. The rachis is about 4.6 to about 8.7 cm. in length,     about 0.1 to about 0.15 cm in width at the widest point, and rough.     The upper side is deeply grooved with few hairs and stipitate glands     on the edges of the grooves. The under side of the rachis is rough     with very few stipitate glands and small prickles. The rachis color     is near 146C on the under side and near 137C on the upper side,     often heavily suffused on the young leaves with near 187B. The     stipules are about 0.9 to about 1.6 cm. in length and of medium     width (about 0.3 to about 0.8 cm.) with moderately short straight     points that usually turn out at an angle of more than 45 degrees and     sometimes recurve toward the stem. The under and upper surface color     of the stipule is between 137A and 137B. The upper and under     surfaces of the stipules are smooth in texture. The petiole is     somewhat light in caliper and rough. The upper side is deeply     grooved with few hairs and stipitate glands on the edges of the     grooves. The under side of the petiole is rough with very few     stipitate glands and small prickles. The petiole is about 0.2 to     about 1.1 cm. in length and 0.1 to about 0.15 cm in width at the     widest point. The petiole color is near 146C on the under side and     near 137C on the upper side, often heavily suffused on the young     leaves with near 187B. The plant displays an above average degree of     resistance to powdery mildew (Sphaerotheca pannosa), downy mildew     (Peronospora sparsa), and rust (Phragmidium sp.) as compared to     other commercial varieties grown under comparable conditions in     Wasco, Calif. The plant's winter hardiness and drought/heat     tolerance are yet to be determined. -   Growth: The plant has an upright somewhat spreading medium height     growing habit (about 115 to about 150 cm. in height and about 66 to     about 85 cm. spread at the widest point), with full branching. It     displays moderately vigorous growth and the canes are of somewhat     light to medium size caliper for the class (about 1.1 to about     1.8 cm. in diameter at the widest point). The color of the major     stems is between 146C and 146B. The major stems are rough in texture     and they bear some large prickles that are about 0.6 to about     1.0 cm. in length. The large prickles are angled moderately downward     with a long somewhat broad oval base; prickle color is near 165B     often moderately suffused with between 201B and 201C. The major stem     bears few small prickles of similar shape and coloration. The color     of the branches is between 146B and 137B. The branches are rough in     texture and they bear some large prickles which are of similar size     and shape to the large prickles on the major stems; prickle color is     between 166A and 165A. The branches bear few small prickles of     similar shape and coloration. The color of the new shoots is between     146C and 146B sometimes lightly suffused with near 187B. The new     shoots are rough in texture and they bear some large prickles which     are of similar size and shape to the large prickles on the major     stems; prickle color is near 152C often moderately suffused with     between 187B and 187C. The shoots bear few small prickles of similar     shape and coloration. 

I claim:
 1. A new and distinct Grandiflora rose plant of the variety substantially as described and illustrated herein.
